Festkolloquium und Oberseminar zu Ehren von Prof. Dr. Dr. h.c. Gerhard Frey

Στις 9 Ιουλίου 2009 διοργανώθηκε Festkolloquium και Oberseminar προς τιμήν του  Prof. Dr. Dr. h.c. Gerhard Frey για την τεράστια συνεισφορά του στην Αλγεβρική Γεωμετρία και την Κρυπτογραφία.

Το συμπόσιο πραγματοποιήθηκε στο Ινστιτούτο Πειραματικών Μαθηματικών (Institute for Experimental Mathematics) στο Έσσεν της Γερμανίας.

Ο  Prof. Dr. Dr. h.c. Gerhard Frey υπήρξε διευθυντής του Ινστιτούτο το οποίο ιδρύθηκε το 1989.

Την ευθύνη της οργάνωσης είχαν οι G. Böckle, H.-G. Rück και G. Wiese.

Ένας εκ των ομιλητών ήταν ο Moshe Jarden, μαθηματικός και καλός φίλος του G. Frey.

Φυσικά, υπήρξαν και οι απαραίτητες φωτογραφίες με το σύνολο των προσκεκλημένων και μια με τους μαθητές του καθηγητή, ανάμεσά τους πολλοί πετυχημένοι μαθηματικοί και κρυπτογράφοι.

Είναι τεράστια η τιμή που τον γνώρισα και υπήρξα μαθητής του για πολλά χρόνια.

Θα ήταν φυσικά αδύνατο να λείπω από αυτή τη συνάντηση.

GTEM 2009: Workshop on Pairings in Arithmetic Geometry and Cryptography

FP6 Research and Training Network GTEM [Galois Theory and Explicit Methods], under the guidance of Herr Prof. Dr. Gerhard Frey, organised a Workshop on Pairings in Arithmetic Geometry and Cryptography at the Institute of Experimental Mathematics.

I am a Junior member of this research group and I participated in the workshop.

The workshop took place at May 4, 5 and 6 , 2009. In the workshop we studied bilinear structures on ideal class groups of curves over finite fields induced by duality theorems of class field theory. Computational aspects as well as applications to public key cryptography were in the center of the talks.

Some of the speakers were P. Barreto, S.Duquesne, D.M. Freeman, G. Frey, F. Hess, D. Lubicz, M. Naehrig, M. Scott and F. Vercauteren.

12th Workshop on Elliptic Curve Cryptography (ECC 2008)

ECC 2008 is the 12th in a series of annual workshops dedicated to the study of elliptic curve cryptography and related areas.

This year the Workshop was held September 22-24, 2008, Utrecht, The Netherlands and was as proceeded by a summer school on Elliptic and Hyperelliptic Curve Cryptography the week before. I spent 6 days in the Netherlands.

I had the chance to attend the summer school and tthe main Workshop.

As the press release states:

Over the past years the ECC conference series has broadened its scope beyond elliptic curve cryptography and now covers a wide range of areas within modern cryptography. For instance, past ECC conferences included presentations on hyperelliptic curve cryptography, pairing-based cryptography, side-channel attacks, voting protocols, quantum key distribution, AES, hash functions, and implementation issues. At the same time ECC continues to be the premier conference on elliptic curve cryptography. It is hoped that ECC 2008 will further our mission of encouraging and stimulating research on the security and implementation of elliptic curve cryptosystems and related areas, and encouraging collaboration between mathematicians, computer scientists and engineers in the academic, industry and government sectors

German-Israeli Minerva School 2008: Arithmetic Geometry and Public Key Cryptography

Durring the summary I participated at the German-Israeli Minerva School 2008. It was as 10-days workshop on Arithmetic Geometry and Public Key Cryptography, organized by Gerhard Frey (Essen) and Moshe Jarden (Tel Aviv) at the Tel Aviv University, 27 July - 4 August, 2008.

In addition the school offered excursion to its participants to Jerusalem (including a guided tour), the the Dead Sea and Massada.

Full list of participants can be found here.

All my expenses were covered by the organisers.

Workshop on Factoring Large Numbers, Discrete Logarithms and Cryptanalytical Hardware

On 22 and 23 April 2008 a workshop on factoring large numbers with NFS and on DL-problems took place at the Institute fuer Experimentelle Mathematik in Essen. The workshop was dedicated to present recent results and exchange ideas in these topics concerning both theory, hard- and software aspects. Organiser was Prof. Dr. G. Frey.

As a member of the Institute fuer Experimentelle Mathematik I participated to the workshop. For me one of the most interesting talks was "Modified Number Field Sieve algorithms for oracle-assisted e-th root  extraction and static Diffie-Hellman problems" by E. Thomé.

Workshop on Arithmetic Geometry

On 22 and 23 January 2008 a workshop on Arithmetic Geometry took place at the Institute fuer Experimentelle Mathematik  (IEM) in Essen.

This workshop was dedicated to recent results and an exchange of ideas in Arithmetic Geometry with a special focus on Galois representations and modular forms.

Organisers were G. Frey and G. Wiese.

Prof. Dr. Frey gave a talk called "Hurwitz Spaces Related to Curves of Genus 2 with Elliptic Differentials"

As a member of the Institute fuer Experimentelle Mathematik I participated to the workshop.

I took some photos:

11th Workshop on Elliptic Curve Cryptography 2007 (ECC 2007) + Tutorial on ECC and HCC

ECC 2007 is the eleventh in a series of annual workshops dedicated to the study of elliptic curve cryptography and related areas. 

This year it was hosted at the Claude Shannon Institute for Discrete Mathematics, Coding and Cryptography at University College Dublin, Ireland.

As the press release states:

Over the past years the ECC conference series has broadened its scope beyond elliptic curve cryptography and now covers a wide range of areas within modern cryptography. For instance, past ECC conferences included presentations on hyperelliptic curve cryptography, pairing-based cryptography, side-channel attacks, voting protocols, quantum key distribution, AES, hash function, implementation issues, and deployments.

At the same time ECC continues to be the premier conference on elliptic curve cryptography. It is hoped that ECC 2007 will further our mission of encouraging and stimulating research on the security and implementation of elliptic curve cryptosystems and related areas, and encouraging collaboration between mathematicians, computer scientists and engineers in the academic, industry and government sectors.

I received a scholarship from the organisers and I had the chance to attend Tutorial on Elliptic and Hyperelliptic Curve Cryptography 2007 which was held September 3-4, 2007, at the University College Dublin. and participate at the 11th Workshop on Elliptic Curve Cryptography 2007 (ECC 2007) that took place September 5-7, 2007 at the same place.
